An Irish ultra runner has revealed a bottle of beer helped him become the only man on the planet to run seven marathons on seven continents in less than five days. ...The 45-year-old admitted sleep deprivation, running, and travelling through different time zones and temperatures took its toll on his body."I was absolutely wrecked. I wasn't even able to keep down water," he said."We came to desperate measures in Sydney and I chanced a beer."I had one bottle of Heineken during the race for some carbs and one at the end of it."It was the first time something stayed down in days."
